AXLE FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent N 0. 674,012, dated May 14, 1901.

Application filed March 1, 1901.

T0 aZZ whom it may concern.-

Be it known that I, FRANK J. NoEoHEL, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Axles for Grain-Drills, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

My invention is an improved axle and as sociated parts of the running-gearing of a grain-drill, the same being hereinafter fully described, and more particularly pointed out in the claims.

One object of the invention is to form the axle in sections and connect the parts so they may have universal motions upon each other.

Another object of the invention is to construct the axle so that the end sections shall be inclined to a horizontal and so as to coincide with the axes of the inclined carryingwheels, the intermediate section being horizontal.

A further object of theinvention is to construct the device so that the spindle holding a carrying-wheel, the latter, and the axlesection at either side of the machine shall be coaxial.

Other advantages and improvements in the device will be brought out in the following specification, reference being had to the accompanying drawings, constituting parts thereof.

Figure 1 is a side view of parts of a graindrill, showing the end of the axle and its connections, parts being broken away and omitted. Fig. 2 is a similar view of the middle parts of a carrying-wheel, further showing the construction, parts being broken away and sectioned as on the dotted line 2 in Fig. 4. Fig. 3 is a view of the central section of the divided axle and portions of the end sections. Fig. 4: is a rear View of the parts, parts being broken away, and the hub of a wheel and associated parts with parts vertically sectioned. Fig. l is drawn to a scale about one-twelfth full size; Fig. 2, to a scale about one-third full size; Fig. 3, to a scale about one-seventh full size, and Fig. 4 to a scale about one-fourth full size.

In the drawings, A A are the carryingwheels of the grain-drill, B the frame, and 0 Serial No. 49,482. (No model.)

the grain-box, mounted upon the frame, all substantially of common construction.

D is my improved axle, consisting of a horizontal middle section Z) and equal end sec tions 0 a, the latter being within the respective hubs d (Z of the carrying-wheels.

E E are spindles holding the carryingwheels, said spindles being secured to the frame B in the usual manner. The outer ends of the hubs d d are expanded and formed with longitudinally outwardly projecting circular flanges c 0, each forming a circular recess 6, Fig. i, in the end of the hub.

The spindles E are inclined downward at their outer ends, as shown, their axes being, respectively, at right angles with the planes of the carrying-wheels they support. end sections a of the axle are centrally within the respective spindles, the latter, the carrying-wheel, and the axle-section at either side of the machine being coaxial. Each section a of the axle projects beyond the outer end of the associated hub, as shown, being provided near its outer end with a circular flanged ratchet f, telescoped within the flange c in the space 2 of the hub.

g, Figs. 2 and 4, is a pawl pivoted to an inwardly-projecting flange h of the hub (Z at the end of the spindle E in position to engage the inwardly-projecting teeth vlof the ratchet. The pawl is so disposed that when the wheel is rolling forward it will cause the pawl to engage the ratchet, and so turn the axle; but when rolling in the opposite direction, as when backing the vehicle, the teeth pass the pawl without turning the axle. A spring is, pressing the pawl, serves to hold the latter in place against the ratchet.

The ratchets ff are rigid with the respective axle-sections a a, being held to place by clamping-nuts 'n n, threaded onto the axlesections, and on account of the concentricity of the axle-sections and the associated parts there is no rocking motion of the ratchets Within the flanges c of the hubs when the vehicle is moving. Then a solid or single-part axle is employed, as is common in this class of machines, with its axis forming an angle with the spindles and the hubs of the carrying-wheels, there is necessarily a universal rocking motion of the ratchets upon the axle.

The p Ioo This is objectionable, for to thus construct the parts they are necessarily made weak and not durable, this being avoided in the construction herewith shown, which is regarded as very important.

As shown in the accompanying drawings, the sections a of the axle are formed with simple hooks Z Z at their inner ends near the ends of the respective spindles passing through eyes m m at the ends of the middle section b, the planes of these eyes being preferably at right angles with each other; but I do not confine myself to this exact method of connecting the sections of the axle, as any other mode of connecting the parts that would admit of slight universal motions upon each other would obviously answer the same purose.

What I claim as my invention is- 1. In combination with the carryingwheels of a grain-drill, an axle for said wheels, consisting of parts or sections movably connected by interengaging hooks and eyes, the axes of said parts or sections of the axle forming a broken line, substantially as shown and described.

2. In combination with the frame and the carrying-wheels of a grain-drill, spindles secured to the frame, and an axle for the wheels, occupying the spindles, said axle consisting of sections movably connected by hooks and eyes with the planes of the eyes at opposite ends at substantially right angles to each other, substantially as and for the purpose specified.

3. In combination with the carrying-wheels of agrain-drill, an axle for said wheels, consisting of an intermediate and extreme sections movably connected, ratchets secured to the extreme sections, and pawls held by the wheels to engage said ratchets, with means for holding the axle, substantially as and for the purpose specified.

4. The frame of a grain-drill, and spindles secured to the frame, in combination with an axle having parts supported in said spindles, and carrying-Wheels held by the spindles, the parts of the axle occupying said spindles being separate and connected by an intermediate part, with movable joints between said parts of the axle with the joints at opposite ends disposed at right angles to each other, substantially as shown and set forth.

5. The frame of a grain-drill, and spindles secured to the frame, in combination with an axle having extreme parts or sections supported in said spindles, and carrying-Wheels held by the spindles, the extreme parts of the axle, occupying said spindles, being separate and connected by an intermediate part or section, with movable joints between said parts of the spindle, the intermediate part of the spindle being horizontal and the end sections inclined downward, circular flanged ratchets telescoped with the flanges of the hubs and clamping-nuts threaded onto the axle-sections and holding said ratchets rigid with said sections, and pawls cooperating with said ratchets,substantially as shown and described.

In witness whereof I have hereunto set my hand this 25th day of February, 1901, in the presence of two subscribing witnesses.
